  • Allows much faster speed and accelerations which increases the economic efficiency of the machines
  • Only one connection line between drive and motor-feedback system. Instead of the encoder cable a specific integrated data pair takes over the signalling.
  • Less cables and reduced connection costs
  • Space and weight savings thanks to hybrid cable design
  • Increased durability under harsh conditions thanks to robust PUR outer sheath
  • Resistant to contact with many mineral oil-based lubricants, diluted acids, aqueous alkaline solutions and other chemical media

Application range

  • Connecting cable between servo controller and motor
  • In industrial robots, moving machine parts or drag chains
  • Automated handling equipment
  • Particularly in wet areas of machine tools and transfer lines
  • Inside of dresspacks of buckling arm robots and for use for gantry robots
  • For indoor and outdoor use
